I took Lamisil for 4 months but was not dieting at the time, but I didn't experience any weight changes or liver problems from it. The Lamisil was very expensive and my Ins. at the time considered it "cosmetic" so wouldn't cover it. My Dr. finally got them to pay for 2 months of it pecause I kept getting infections under the corners of the nails

Since then (5 years), I had 1 nail turn thick again and fall off. I used Melaluca oil (Austrailia Tea Tree) on it and it and it has grown in healthy. A nurse practioner told me a couple of weeks ago that Vicks Vapor Rub works too.
